98 land rover discovery v8 petrol last time it did this i replaced plugs and ran fine been running great until now ?
Get a used spark plug and hook it to a sparkplug wire and have someone crank it over and ground the plug and see if it sparks if it don't you have a problem with the computer or electronic ignition. Or it could be that it jumped timing.

Check the distributor position when the engine is turned to TDC , the rotor should be facing close to no. 1 spark plug lead.Try spray some quick start spray in the inlet and see if it takes , if so then your fuel return is dumping too much fuel.The older pressure regulators were adjustable by a small screw next to the diaphragm.

This site has a lot of information regarding your Discovery including pricing, specs etc. I suspect you can find what you need here:

I was going to write that typical fuel pressure ranges somewhere between 15 & 25# and would have been 12# low.
Guess checking before pretending expertise is wise . . .

Sounds like the fuel filter is dirty and needing to be changed. It's cheap and easy to swap out.
